Far Infrared Emissivity Characteristics and Evaluation of Different Light Source Irradiate Polyester Knitted Fabric

In this Study, Visible on the Far-infrared Emissivity of Knitted Fabric, its Rate of Change of Far Infrared Radiation Were Observed. in this Study, Light Exposure Time for 20,40,60 Minutes, the Experimental Results, the Longer the Kind of Light Source Distribution Is much Higher Surface Temperature Will Be Relatively Higher Rate of Infrared Radiation, when the Light Source when the Suspension Began Measuring Data, the Light Source, the Far Infrared Radiation Rate of about 0.941 ~ 0.975 when Reached Will Begin to Flatten, after 15 Minutes Returned to its Emission Rate of about 0.937, when the Far-infrared Light Irradiation of Polyester Fabrics through the Far Infrared Radiation Values Are Effectively Increase, so the Light Irradiation Intensity of Far Infrared Radiation Rate of the Subjects Were Characterized by Light and the Length of Time to Improve the Fabric Surface Temperature Change and this Temperature Rise Is the Key to the Experimen
